Variable Message Signs (VMS)

Variable Message Signs, powered by SWARCO, provide pertinent roadside information and warnings to en-route motorists through high quality, full-color LED displays. Strategically placed, these signs improve overall traffic flow and commuter safety. Commonly used VMS applications include safety information near airports and major venues, data regarding road closures or detours, direction and availability of carpool lanes or toll roads, advisory phone numbers, and general alerts.
